RoboBall—One-servo Robot
Maker Faire Bay Area 2026
September 25th-27th
RoboBall explores how much a robot can do with the bare minimum. With just one servo driven by a tiny microcontroller, this simple sphere becomes surprisingly capable—and fun. Draw and customize your own RoboBall, then use your phone to drive, race, or even wrestle with friends and family, all while discovering the power of minimalist robotics.
